I am designing a PCB for a self-powered industrial device with a USB port, and therefore need to use VBUS sensing. In the generic USB hardware guideline (application note 4879), it is stated that "Pin PA9, a five V-tolerant pin, is natively dedicated...
I have designed an audio device based on a STM32H743 MCU. For synchronization purposes I need to be able to count incoming USB frames.To achieve this, I use TIM5 in slave mode, with ITR8 as its trigger. The results are puzzling. I am getting either 1...
I am struggling to find working examples to work with FreeRTOS in an interrupt mode.I use the function HAL_I2C_Slave_Transmit_IT() This enables the interrupt as well as setting up the data.It works to a point, then the remote Master send a Nak and 8 ...
I am trying to send some communication from an Nucleo-F412ZG board over USB. I am currently using CDC_Transmit_FS function but this seems to only send char values and I would like to be able to send an uint8_t variable and have it come out as a meani...
Greetings !I am trying to incorporate TLS functionality on STM32H743 . I have tried implementing sample TLS Server Application on STM32H and I could able to send and receive data using simple TLS client which is developed using Python.Now I am trying...
Hi community, I am trying to use a Nucleo-L053R8 board to send data over USB without much success. The purpose of my project is simply to test the USB communication by sending string over USB Port as a first step before sending the sensor data. When ...
Hi all,Hardware - STM32L4R9 Disco with STEVAL-MK172V1 eCompassI'm stuck trying to resolve some kind of conflict I'm having with Hal_Delay. I've lowered the priority of the timer interrupt so that SysTick is a higher priority. I've tried using both th...
I made an I2C communication between STM32U585 uC to an I2C EEPROM and it worksI do the following but if I remove the HAL_Delay(10) or minimizes it to less than 10msec things are not working well, the second call I2C_Master_Transmit fails.Is there's ...
Currently, I am using the STM32L162VE custom board. I want to enter the USB DFU mode but am not able to enter the mode. This chip supports the USB and USART pre-programmed bootloaders. I have referred to the application notes AN2606 and AN3156. I did...
